Application fired February 1, 1922. seri-.11110. 533,349.

This invention relates to improvements in neckband expanders used inconnection with `the ironing of shirts and more particularly rthe typeused to expand the neckbands of shirts having collars attached.

' The objects of this invention are to provide a neckband expander withan improved clamping clip together with means for lock-Y ing the Clip inclamping position; and more specifically to4 provide a `locking meansnwhich has pivotal and sliding movement for releasably locking the clipin clamped posi- 'l tion.

y Other yobjects of the invention lwill Vbe 4 apparent from thefollowing, description and claims 4,when considered togetherY with theaccompanying drawings. i o

The guide 1 is suitably mounted upon the V main table or support. 2 .andis provided with the bracket 3 for support of the guide plate 4 for'theneckband former. The ironing table 5 ismounted upon the support 6 v*which has sliding movement upony the main the neckband former isindicated at 7 while "the rear portions 7 are adapted for adjusta-` blemovement according to the shape and size ,of the neckband ofthe shirt.lhe ad'- justable extensionblocks 7.have slidable movement Yin onedirection bymeans of their' guidepins8 engaging the main stationarypart'V ofthe-'neclrband former and'in the otherdirection along theguidepin 9 which extends Ythrough the top portionl of the yoke gplat-e '10,and is secured thereto by means ot' theset4 screw 11'. The mechanism foroper- :ating the yoke` ironingrv member 10a forms no part of the presentinvention. The pins 12 extend through theguides 13 and through the`stationary portions 7 of the neckband expander whereby it ispossiblefor the neckband expander to yield downwardly as mayl be necessaryduring the ironing operation, the upper rear ,portions of the-ironingtable 5 being cut Vdown as indicated at 5f? to perimit such depressionof the neckband expander during the Ironing operation.' The springs 12aare providedyfor the pins 12.,v

guide plate 4 and the main part of the neckband expander. The pins 12extendalso through the brackets 15 secured to the underside of the guide'plate' 4. Slidably band expander there is provided the bracket 17 whichhas the ribs 18 engaging in the' `slots 19. The bracket 7a on the mainvVpart 7.0i the neckband former has a projection surrounded byfspringj17athe other end of which abut-s the bracket 17. ,e Pivotally lmounted atthe point20 upon ingengagement with the front lportion of the neekbandot the shirt. The locking -member 22 is provided with a slot.` 23gforslidable engagement-with they flat `faces ofV to have vthe slot 23engage the iiat'aces ot the pivoty 20, thereby preventing raising of theclip 21. y

The vguide pin 28, which extends through the expander 7, is connected atlits oneV end 'these springs having `abutment against lthe "mounted-uponthe main part of the neoky with the screw 29 secured in the slidingbracket 17 while the other end of the pin 28 extendsthrough the opening30 in the yoke plate 10. rThe pin 28 extends valso through the dependingarm of the guide pin .lockBl which is provided with thebutton `32 formanipulation thereof. The lower end of the lockx31 vengages inthe-recess 32` formed in the slide 38 which is mounted in the neckbandformer. The guide. pin 28 is provided with a shoulder 34 for engagementby the opening in the lock member 31,V that is, upon sliding adjustmentof the bracket 17 after the clip 21 has been lowered toengagetheneckband of the shirt. rEhe spring f 35 tends to hold the lock 31 inengagement with the shoulder 34. The stop collar 3G which is mounted inthe neckband expander is adapted to be engaged by the stop point of thescrew 29 land `also by the. stop screw 37 which is provided upon theslide 33.

The slide 33 is adjusted by means of the bell crank vlever 38, the upperend of which has pivotal connection with the slide 38 at the point 89. YThe pin 40 carried by the bell crank lever 38 engages the verticalgrooves 41 formed in the sides of the depending brackets 15, therebyproviding` a pivot point for the bell crank lever. The lower end of thelever 38 has pivotal connection at 43 with the shackle 44 carried by oneend of the rod 45. The rod 45 carries a swivel block 45 which can beslid thereon against the tension of spring 47 whose other end abutsagainst the nuts 48 carried by the rod 45. The collar 49 on the rod 45limits the movement of the swivel block in the other direction. The arm50 of the bell crank lever 51 has pivotal connection with the swivelblock 46 and is provided with the rollers 52 which are adapted forengagement by the cam 53 which is mounted upon the shaft 54-and can beoperated by the lever arm 55. The segmental gear 55 which is alsomounted upon the shaft 54has meshing engagement with the companionsegmental gear 57 mounted upon the shaft 58 which carries also the arm59 with the roller V60 for engagement with the sliding support 6.

After dressing the shirt upon the ironing board, the clip 21 is loweredso as to engage the neckband, the lock 22v having been adjusted topermit pivotal movement of the clip. The locking member 22 is then slidinto locking position so as to prevent raising movement of the clip, andthe bracket 17 is slidably adjusted against the tension of spring A17aso as to cause the shoulder 84 to be engaged by the edge of the openingthrough the arm of the locking lever 31, the spring 35 tending to holdthe lever 31 in such engagement. This movement of the sliding bracket 17tends to further clamp the clip 21 in engagement with the fronty portionof the neckband. rlhen upon raising the lever 55, the cam 53 will engageone of the rollers 52 so as to cause rockingl movement of the bell cranklever 51 and movement of the arm 50 to the right as viewed in Fig. 1.The spring 47 isthereby placed under tension and the rod 45 is moved tothe right, causing` the slideV 33 to move to the left, as viewed in Fig.3. By

virtue ofthe engagement of the lever 31 in the notch 32 together withthe engagement of the lever 31 with the shoulder 34, the movement ofslide 38 causes firm clamping action'of the clip 21. rilhis action takesplace prior to the engagement of the roller GO with the sliding support6. Further operation of lever 55 will, through gears 56 and 57, causeengagement of roller 60 with .support 6 so as toniiove the ironing tableand yoke plates to the left as viewed in Figs. 1 and 3. At the sainetimethe rear portions of the neckband former are eX- tended according tothe sizeV and shape of the neckband which is thereby. placed undertension. The shirt is then in condition for the ironing operation.

Upon completion of the ironing operation7 the lever 55 is lowered so asto cause the roller 60 to engage the web to return the support 6to theposition shownin Fig. 1, and to relieve the tension on the neckband ofthe shirt. Depression of the button '32 will release the engagementbetween the lever 31 and the shoulder 34, whereupon the spring 17L willforce the sliding bracket 17 to the right, as viewed in Fig. 3, therebyrelieving the clamping action of the clip 21. rEhen upon slidingadjustment of the locking member 22, so as to bring the end portion` 27of the slot to surround thepivot pin 20, the clip 21 can be raised so asto altogether release the neckband of the shirt.

Since the ironing` board has an angular pitch, as illustrated in thedrawings, it is possible to employ my present invention to iron a shirthaving an attached collar as well as the ordinary shirt without thecollar; since, upon applying tension to the neckband,` the attachedAcollar is caused to lie on the angular surface and will not be damagedby the engagement ofthe ironing chest. rlhe operation is the same in thetwo position to said support, yielding means opposing inward movement ofsaid support toward the center vof said former, and means arranged tohold the support when moved to its inner position.
